if you could answer this question i'd be very grateful!
In a hot water system water is heated by burning gas in a boiler. The hot water is then stored in a tank. For every 111 J of energy released from the gas, 100 J of energy is absorbed by the water in the boiler.
a) calculate the percentage efficiency of the boiler. (show working +formula).
b) the energy released from the gas but not absorbed by the boiler is 'wasted'. explain why this energy is of a little use for further energy transfers.
c) The tank in the hot water system is surrounded by a layer of insulation. Explain the effect of the insulation on the efficiency of the hot water system.
